I got a museum client. They are an A list (whale) client. They eventually always pay, but are constantly overlooking invoices, not paying on time, making mistakes, and it is really starting to bug me. Problem is I can not afford to let them go. I've tried waiting, checking in with them weekly, but its at a point where I don't know what to do?? Are late fees / charges something sign makers do? What about a contract?
